From reading threads in this forum I understand it's not possible to run dual 4K MST (i.e. Dell 2414Q) monitors both at 60Hz due to Thunderbolt bandwidth limitation. But how about dual SST 4K monitors, will it work with riMac 27" @ 60Hz? The closest information I can get is from this thread: https://discussions.apple.com/thread/6868583 The gent says he's able to do it with his rMBP 13". Has anyone tried with riMac? Advice appreciated.
